To all/whom it may concern Be it known that I, HUGH'DALEY, a citiandaresident of Chicago, Cook count-y, `State of Illinois, have inventedcertain new and useful Improveniente` in Hydrocarbon-Burners; and I dohereby decla-re that the followingdescription of my said invention,taken in conne'ct-ion with the accompanying -sheet of drawings, forms afull, clear, and exact specification', which will enabl others skilledin the art to which it appertains to make and use the same. i

My invention relates to improvement-s in hydrocarbon burners, and itconsists, essentially, in the novel and peculiar' comhina-tion of partsand details of construction, as hereinafter' iirst fully set forth and'-The object of my invention is the produc-f tion of a simple andeiiicient portable surface heater which may be easily propelled by hand.horse power, or, by attachment toa. suitable motor truck, for thelparticular purpose of melting snow on rural delivery postal routes, oncity streets and alleys, and on sidewalks. In the first namedemployment, ymy invention can be attached o either front or rear of asuitable motor vehicle, and pushed or pulled, as the case may be, oversnow clogged roads. The lintense heat generated by my device, which, inacxtual use, will coveran actual area of about 30 square feet, willalmost instantaneously melt all snow Wit-hin its area of operation, andthe resultant water gutters at the side of the road. In the case of widecountry roads, two or more of these devices may be employed to serve theentire width of the road. l

In practice, these devices are started out after a few inches of snowhave fallen and follow the storm, returning over the saine route afterreaching the end of their run.

Atourv hours by each device.

will ow into the Asthe outfits are'ar'ranged to travel at the rate oftwo miles an hour, it is evident that a large territory can be coveredin twenty l In like manner my motor vehicle drawn heater may -beemployed to dry muddy postal routes during the wet, springI season, thewater on such roads being evaporated into steam and dissipated in thesurrounding atmosphere.

Regular trips over such roads at stated in- Will convert the same frompracti'- tervals,

cally impassable thoroughfares into goedA lanes of traiiic in a shortspace of time.

'Large municipalities spend .enormous sums of money every winter forsnow removal from its thoroughfares., With the employment of a series ofmy outfits, ac,- companie'd by a suiiicient squad of swabbers behind toswab the melted snow into the nearest sewer manholes, streets may be lcleared at the rate-of two miles per hour andthe Water disposed ofthrough the sewers at. a fraction of' the present expense.

Smallmaehines, hand' proplled, may also be used for clearing snow a icefrom sidewalks, and, still another 'applicationis the softening ofasphalt around breaks in streets for the `purpose of making repairs.

-In the drawings hereinbefore mentioned, I

illustrate my device as constructed for handl propulsion, but I Wish itunderstood that the same may be vehicle propelled without l themodification of any essential elements.

In Fig. l, I show a bottom plan of one of a series of hydro-carbonburners A, in which l is the hydro-carbon fluid. inlet, which inletcomprises a cross 2, or the like, 'the' side branches 3 and 3a of whichcommunicate with Ts 4 and 4a by means of close nipples 5 and 5, The Tsli-andl"1L in turn, oonnect with elbows 6 and 6a through similarnipples7 an'd 7a. The slde openings of said cross, Ts, and elbows point in the'same direction; e., toward the rear of the heater, all of whichconstruction is located transversely at the front end of the heater.From the Ts 4 and 4 and elbows 6 and 6n lead longitudinal. 9, 10', and11, all .of which are closed at their free ends by 'suitable caps 8, 9",10, and 11, relationship by a supporting bar 12', so'as to support saidfiam'e tubes and maintain them in parallelism. The walls of said tubes,on their under sides thereof, are-pen forated by a multiplicity of,minute, closely horizontal Haine tubes 8,'

which caps are maintained in xed ilo - matter.

spaced holes 13, extending the entire length of the same. Directly underthese perforations are located metallic strips or so called battle bars15, for purposes hereinafter described.

Leading from the cross 2, above mentioned, between and parallel to flametubes 9 and 10, is a similarly downwardly perforated flame tube 16.Thistube is surrounded by a jaeketing tube 16, made from brass or othermetal of high heat conductivity, which tube is provided withperforations 17, registering with the perforations 17B, in the flametube 16. This tube is capped at its free end, as are the others, by acap 18a, which cap is similarly fastened to the supporting bar 12,already referred to.

Extending the entire length underneath the elbows G and G, the nipples 7and 7, Ts fand 4a, nipples 5 and 5, and cross 2 is a metallic, more orwhich isadaptcd to contain a quantity of liquid hydro-carbon, whichlwhen ignited will cause volatilization,by transmitted heat, of amixture of hydro-carbon liquid a-nd oxy Gen introduced into the saidparts through the inlet -member opening 1 of the cross 2, and passingthrough them into their respective flame tubes 8, 9, 10, and 11. If themixture is not thoroughly volatilized when it enters these tubes, theliquid portion thereof will drip through the openings 13 onto the up-`per surfaces of the baffle bars 15, where said liquid will be ignited bythe flame issuing from cup 18. The llames upon all of these bars .15will, in a very-few seconds, heat the pipes 8, 9, 10, and 11 untilcomplete volatilization is attained, after which llames of intense heatvalue will issue from all of the openings 13. AThese flames beingprojieeted downwardly are split apart, as it were, by the baille bars 15and caused to spread on either side thereof, so that' the fl'ames fromone of the llame tubes will impinge upon the flames from tubes` adjacentthereto on both sides, so that the area beneath the burner A iscompletely covered Y by a flame of intensepheat value.A The jacket 16a,surrounding flame tube 16, serves the same purpose as the ballie plates15, but accomplishes the result much more rapidly. The unvolatilizedliquid dropping through perforations 17 `and 17, ignite at the peripheryof the jacket and the resultant flame completell surrounds the saine,thereby more quickly heat-ing the interior tube 1G in an obvious manner.rIhe object in more rapidly heating flame tube 1G is that the mixtureenteringl through :inlet l, following the lines of least resistance,will more readily enter said tube, and must, therefore, be 4more quicklyconverted into volatilized 4A series vof tkwo or more of these burners"are mounted in parallel within and near.

T he said rear and front ends are providewith a plurality of openings 22 and 22, adapted to be closed by slidingcovers 23v and 23, so as to regulate the admission of the proper amountof oxygen to insure per- To the end Wall 21a, at a. point slightly belowthe inlets 1 of the burners A, are located brackets 24, supportingneedle valves and bodies 25, the nozzles 26 of which are in' axialalinement with said inlets 1. From these needle valve bodies leadupwardly converging hydrocarbon tiuid'supply pipes 2.7 and 27, whichterminate in a Y- haped casting 28, from which extends a main supplypipe 29, entering a fuel tank 29, located on the top of the hood B. Astop valve 30 is introduced in the fuel liney 29 for evident reasons.The hood B may be mounted upon wheels C and C, revolving upon axles andaxle brackets 31 and 31, in which case a stiftening member 32 isfastened on the interior of the hood to render the sides 19 and 19 morerigid. In the fuel tank 29n is located an air pump 33 to createvsuiiicient pressure, within said tank, to force the liquid fuel throughthe nozzle 2G ofthe needle valve and body 25 into the inlet 1 of theburner or burners A in a state of semi-atomizl'ation.

For the purpose of propelling the complete device byhand, by horsepower, or by attachment to a suitable motor vehicle, as hereinbeforevdescribed, are provided handles, shafts, or attachments 34. Any form ofattachment to a prop lling truck may be employed.
